This Makefile can be used to download various UK shapefiles and convert them to geojson and topojson formats. Currently we have:

• UK boundary.
• UK wards.
• England and Wales OAs, LSOAs and MSOAs.
• Scottish Datazones (equivalent to LSOAs) and Intermediate zones (MSOAs).
• England, Wales and Scotland postal areas and postal districts.
• England, Wales and Scotland counties and bouroughs.
• Ordnance Survey (OS) Boundary Line shapefiles ("electorial and administrative boundary information").
• OS Strategi ("a regional overview of road networks, railway lines, cities and rural wooded areas").
• OS Meridian 2 ("customisable for communication and topographical themes and route planning").
• English Green Belt 2011 regions.
• UK police force and fire service areas.
• Primary Care Organisations, Strategic Health Authorities, Clinical Commissioning Groups.

Run 'make all' to produce them. Required packages: topojson and ogr2ogr (gdal library).
